Trust me when I say Blue Cube's advice about not doing the day and night thing until you are a bit more familiar with RM2K3 is very wise. Due to such things would be great games are abandoned. "Think inside the box, everyone else is too busy trying to think outside it." (De'vo Vom Schattenreich) But if you still want to do it try Gaming World, they have a few tutorials on it (sorry I'm too lazy to type one out for you myself). Hope that helps, good luck my friend.
